ValueProcessorOptions

Options object for ValueProcessorByRule functions.

Properties​

concatOperator?​

optional concatOperator: string & object | "||" | "+" | "CONCAT"

Operator to use when concatenating wildcard characters and field names in "sql" format. The ANSI standard is ||, while SQL Server uses +. MySQL does not implement a concatenation operator by default, and therefore requires use of the CONCAT function.

If concatOperator is set to "CONCAT" (case-insensitive), the CONCAT function will be used. Note that Oracle SQL does not support more than two values in the CONCAT function, so this option should not be used in that context. The default setting ("||") is already compatible with Oracle SQL.

Default​

'||'

Inherited from​

FormatQueryOptions.concatOperator

Defined in​

packages/react-querybuilder/src/types/importExport.ts:186

escapeQuotes?​

optional escapeQuotes: boolean

Defined in​

packages/react-querybuilder/src/types/importExport.ts:198

fallbackExpression?​

optional fallbackExpression: string

This string will be inserted in place of invalid groups for non-JSON formats. Defaults to '(1 = 1)' for "sql"/"parameterized"/"parameterized_named" and '$and:[{$expr:true}]' for "mongodb".

Inherited from​

FormatQueryOptions.fallbackExpression

Defined in​

packages/react-querybuilder/src/types/importExport.ts:122

fieldData?​

optional fieldData: FullField<string, string, string, Option<string>, Option<string>>

The full field object, if fields was provided in the formatQuery options parameter.

Defined in​

packages/react-querybuilder/src/types/importExport.ts:203

fieldIdentifierSeparator?​

optional fieldIdentifierSeparator: string

When used in conjunction with the quoteFieldNamesWith option, field names will be split by this string, each part being individually processed as per the rules of the quoteFieldNamesWith configuration. The parts will then be re-joined by the same string.

A common value for this option is '.'.

A value of '' (the empty string) will disable splitting/rejoining.

Default​

''

Example​

formatQuery(query, {
  format: 'sql',
  quoteFieldNamesWith: ['[', ']'],
  fieldIdentifierSeparator: '.',
})
// "[dbo].[Musicians].[First name] = 'Steve'"

Inherited from​

FormatQueryOptions.fieldIdentifierSeparator

Defined in​

packages/react-querybuilder/src/types/importExport.ts:88

fieldParamNames?​

optional fieldParamNames: Record<string, string[]>

Included for the "parameterized_named" format only. Keys of this object represent field names and values represent the current list of parameter names for that field based on the query rules processed up to that point. Use this list to ensure that parameter names generated by the custom rule processor are unique.

Defined in​

packages/react-querybuilder/src/types/importExport.ts:216

fields?​

optional fields: FlexibleOptionList<FullField<string, string, string, Option<string>, Option<string>>>

This can be the same FullField array passed to QueryBuilder, but really all you need to provide is the name and validator for each field.

The full field object from this array, where the field's identifying property matches the rule's field, will be passed to the rule processor.

Inherited from​

FormatQueryOptions.fields

Defined in​

packages/react-querybuilder/src/types/importExport.ts:106

format?​

optional format: ExportFormat

The ExportFormat.

Inherited from​

FormatQueryOptions.format

Defined in​

packages/react-querybuilder/src/types/importExport.ts:34

getNextNamedParam()?​

optional getNextNamedParam: (field) => string

Included for the "parameterized_named" format only. Call this function with a field name to get a unique parameter name, as yet unused during query processing.

Parameters​

ParameterType
fieldstring

Returns​

string

Defined in​

packages/react-querybuilder/src/types/importExport.ts:221

numberedParams?​

optional numberedParams: boolean

Renders parameter placeholders as a series of sequential numbers instead of '?' like the default. This option will respect the paramPrefix option like the 'parameterized_named' format.

Default​

false

Inherited from​

FormatQueryOptions.numberedParams

Defined in​

packages/react-querybuilder/src/types/importExport.ts:154

paramPrefix?​

optional paramPrefix: string

This string will be placed in front of named parameters (aka bind variables) when using the "parameterized_named" export format.

Default​

":"

Inherited from​

FormatQueryOptions.paramPrefix

Defined in​

packages/react-querybuilder/src/types/importExport.ts:129

paramsKeepPrefix?​

optional paramsKeepPrefix: boolean

Maintains the parameter prefix in the params object keys when using the "parameterized_named" export format. Recommended when using SQLite.

Default​

false

Example​

console.log(formatQuery(query, {
  format: "parameterized_named",
  paramPrefix: "$",
  paramsKeepPrefix: true
}).params)
// { $firstName: "Stev" }
// Default (`paramsKeepPrefix` is `false`):
// { firstName: "Stev" }

Inherited from​

FormatQueryOptions.paramsKeepPrefix

Defined in​

packages/react-querybuilder/src/types/importExport.ts:146

parseNumbers?​

optional parseNumbers: boolean

Renders values as either number-types or unquoted strings, as appropriate and when possible. Each string-type value is evaluated against numericRegex to determine if it can be represented as a plain numeric value. If so, parseFloat is used to convert it to a number.

Inherited from​

FormatQueryOptions.parseNumbers

Defined in​

packages/react-querybuilder/src/types/importExport.ts:161

placeholderFieldName?​

optional placeholderFieldName: string

Any rules where the field is equal to this value will be ignored.

Default​

'~'

Inherited from​

FormatQueryOptions.placeholderFieldName

Defined in​

packages/react-querybuilder/src/types/importExport.ts:167

placeholderOperatorName?​

optional placeholderOperatorName: string

Any rules where the operator is equal to this value will be ignored.

Default​

'~'

Inherited from​

FormatQueryOptions.placeholderOperatorName

Defined in​

packages/react-querybuilder/src/types/importExport.ts:173

preset?​

optional preset: SQLPreset

Option presets to maximize compatibility with various SQL dialects.

Inherited from​

FormatQueryOptions.preset

Defined in​

packages/react-querybuilder/src/types/importExport.ts:190

quoteFieldNamesWith?​

optional quoteFieldNamesWith: string | [string, string]

In the "sql", "parameterized", "parameterized_named", and "jsonata" export formats, field names will be bracketed by this string. If an array of strings is passed, field names will be preceded by the first element and succeeded by the second element.

A common value for this option is the backtick ('`').

Tip: Use fieldIdentifierSeparator to bracket identifiers individually within field names.

Default​

'' // the empty string

Examples​

formatQuery(query, { format: 'sql', quoteFieldNamesWith: '`' })
// "`First name` = 'Steve'"
formatQuery(query, { format: 'sql', quoteFieldNamesWith: ['[', ']'] })
// "[First name] = 'Steve'"

Inherited from​

FormatQueryOptions.quoteFieldNamesWith

Defined in​

packages/react-querybuilder/src/types/importExport.ts:67
